Mowers: Neighborhood kids that need an extra five bucks. Because I would spend that in gas/electric alone to cut my yard. Saves me time and energy. Makes the world greener too.

Snow throwers? Same boat, just different season. Gosh, kids these days will do anything to pay for that WoW/SWTOR account.

Gas. I own both, but the electric one is just a huge pain to use. Dragging around 200' of heavy gauge extension cord only to have the mower choke if the grass is a little too long or thick just isn't worth it. Needless to say, come spring time, the electric mower is gone.

I've never used a cordless electric... That just sounds like a bad idea to me. I know I'll kill the battery storing it in the shed every winter. Plus, I have a big yard. I find it hard to believe it can last long enough to provide consistent energy for the job on one charge.

(edit: And I meant push mower in my prior post. Missed the edit window there. Though it is powered by push power.)

Gas, self-propelled.

I have both a gas and electric mower. I use the battery powered electric mower the most. However it's not too powerful, so I have to use the gas push mower, when I've gotten lazy and the grass has grown too tall. I really don't like mowing the lawn. :(

I have a cordless electric mower that I really like. Got it cheap through a deal from the city (turn in your old, earth killing gas mower, get a voucher for a giant discount on the expensive cordless electric). It works really well for me. I do have a small yard (about 1/8th acre) and mow often enough that I don't have a lot of big weeds/brush to deal with. I like that the mower is light and easy to turn around in small spaces. I also like that it's really quiet.
Unless I move to a house with a bigger yard, I don't think I'll ever go back to a gas mower.

I have both and use both. I almost always use the cordless electric mower on the yard around the house. It cuts cleanly and mulches the grass, an I can usually cut the whole yard before the battery needs recharging. I've had it for 4 years and have never had a problem with the battery. The only problem is that the battery need to be recharged for about 16-18 hours after using it, so I have to wait a day if I still have more yard to mow. I could get an extra battery, but I'm not in that big a rush.

I use an old gas mower for clearing the pathways down to the barn and outbuildings, and the weeds in the garden. Since the ground can be uneven and damp, the electric mower doesn't work as well there. Also, the gas mower can self-propel and the electric can't (though there are electric mowers that can.)
